 If you have more than one module, and you want them to be compiled into elf filethen:
 Let's assume we have module M0 which imports M1;
 
-voc -l M1.Mod -s M0.Mod -M
+>voc -l M1.Mod -s M0.Mod -M
 
 Here -l is a global option.
 Module M1 will be compiled with -s option, i. e. sym file will be generated.

 In case you have modules in different directories, like "ui", "logic", "math", then you need to export MODULES environment variable like this:
 
-export MODULES=".:ui:logic:math"
+>export MODULES=".:ui:logic:math"
 
 and after call voc
 
-voc -s ui0.Mod
+>voc -s ui0.Mod
 
 Otherwise you can use full path:

+=========

+if you'd like to build an rpm installer, then
+
+* compress sources as voc-1.0.src.tar.bz2
+* put them to /usr/src/redhat/SOURCES/ (or other similar location)
+* run "rpmbuild -ba voc.spec
+
+this should create voc rpm installers.
